André Hoevel initially studied economics and gained commercial experience in the USA. He met his future wife Anneliese in Berlin, where she was working as a secretary. When André Hoevel was given a leading position at Opel in Rüsselsheim, the couple moved to Wiesbaden in 1930. They joined the KPD in 1932.

After the seizure of power in 1933, André Hoevel was dismissed and had to go into hiding. In Frankfurt, he built up the illegal work of the KPD. From this point on, Anneliese Hoevel led the women's group of the Wiesbaden KPD. She was arrested for the first time in September 1933 and interned in the Moringen women's concentration camp. André Hoevel was also arrested at almost the same time. Anneliese Hoevel continued her political work after her release, but after six months she was exposed by an informer, sentenced to three years in prison and interned in women's concentration camps. André Hoevel was sent to the Esterwegen, Sachsenhausen and Buchenwald concentration camps.

Released in December 1938, he went to Koblenz with his wife, who was also set free. Still convinced of the need to fight against the Nazi state, the couple, together with their friends Mr. and Mrs. Noetzel, established contacts with communists, social democrats and members of the middle-class opposition, including members of the Centre Party - from the Rheingau to Koblenz and the Ruhr area. After the war began in 1939, they gathered information about the crimes in the East and listened to "enemy broadcasts". They disseminated their knowledge in letters that they sent by post to German soldiers.

In 1941, the Gestapo arrested both couples. The Hoevels were sentenced to death for "high treason" in a show trial in Frankfurt am Main and subsequently executed in Frankfurt.

"The spirit that inspired them, the belief in the right to rebel against state injustice, has also found expression in our constitutional law", declared the Hessian Minister President Georg August Zinn in 1962 at the inauguration of a memorial in Frankfurt's Preungesheim prison in memory of André and Anneliese Hoevel.
